Adsorption of 4-Nitrophenol onto Iron Oxide Bentonite Nanocomposite: Process Optimization, Kinetics, Isotherms and Mechanism
( Springer Science and Business Media Deutschland GmbH , 2022 , Article)Despite its importance in chemical industry, 4-Nitrophenol (4-NP) is a persistent organic pollutant that has serious effects on the ecosystem. In the present study, Box–Behnken design in response surface methodology was ... -
Choline chloride based natural deep eutectic solvent for destabilization and separation of stable colloidal dispersions
( Elsevier B.V. , 2021 , Article)In solid-liquid separation processes, coagulation/flocculation is one of the most popular techniques in treating wastewater, as it is efficient, simple, and economical. Consequently, the formation of a new environment ... -
Destabilization of stable bentonite colloidal suspension using choline chloride based deep eutectic solvent: Optimization study
( Elsevier Ltd , 2021 , Article)Choline chloride (ChCl) based natural deep eutectic solvents (NADES) were synthesized and tested as coagulant for stable bentonite colloidal suspensions. In this work, three ChCl based natural deep eutectic solvent NADES ... -
Effect of charge type and density of polyacrylamide on the electrokinetics behavior of flocculated bentonite suspensions
( AIChE , 2016 , Conference)The study of electrokinetics behavior of clay suspensions is of fundamental importance in many industrial applications. This paper addresses the electrokinetics behavior of polyacrylamide (PAM)- bentonite suspensions. The ... -

( Elsevier Ltd , 2018 , Article)© 2018 Elsevier B.V. In this study, the influence of electrolytes on bentonite dispersions flocculated with different polyacrylamides varying in charge type, density and molecular weights has been investigated. The presence ... -
Enhancing the flocculation of stable bentonite suspension using hybrid system of polyelectrolytes and NADES
( Elsevier B.V. , 2022 , Article)In this study, the influence of a hybrid coagulation/flocculation process on the electrokinetic of highly stable bentonite suspension has been examined. Choline chloride (ChCl) based natural deep eutectic solvent (NADES) ... -
Impact of aluminium acetate particles size on the gelation kinetics of polyacrylamide-based gels: Rheological and molecular simulation study
( John Wiley and Sons Inc , 2021 , Article)Inorganically crosslinked polymers have been intensively implemented for conformance control treatments in oil and gas wells at low temperatures (<90°C) because of their faster gelation time compared to organically crosslinked ... -
Influence of choline chloride based natural deep eutectic solvent on the separation and rheological behavior of stable bentonite suspension
( Elsevier B.V. , 2021 , Article)Colloids in wastewater are considered a serious problem due to their stability and separation difficulty. Coagulation/ flocculation processes are the most common for the separation of colloids because of their high-performance ... -
Influence of combined natural deep eutectic solvent and polyacrylamide on the flocculation and rheological behaviors of bentonite dispersion
( Elsevier , 2022 , Article)The influence of hybrid coagulation/ flocculation systems on the degree of flocculation and rheological behavior of highly stable bentonite suspension has been investigated throughout this study. Natural deep eutectic ... -
Influence of polyelectrolytes and other polymer complexes on the flocculation and rheological behaviors of clay minerals: A comprehensive review
( Elsevier B.V. , 2017 , Article Review)Separation of clay minerals from industrial wastewaters is of great academic and practical importance. Current treatment techniques are either not economically viable, not environmentally friendly, or both. Thus, researchers ... -
Intercalation of ionic liquids into bentonite: Swelling and rheological behaviors
( Elsevier B.V. , 2016 , Article)In this study, direct intercalation of three different green ionic liquids (ILs) having different salt and cation sizes into bentonite interlayer is investigated. The ILs covered in this study are: 1-hexyl-3-methylimidazolium ... -
